The way I think about it, and how I might end up enjoying it... Is, my favorite parts of Rise of the Resistance are everything leading up to the actual ride... Now, imagine a two day vacation that's just that stuff.. Fake shuttles to/from a big ship. Kylo Ren boarding and causing a scene. A space battle happening outside our windows. It could be really neat.
It's the sleeping in bunks overnight in the illusion of being in space that worries me. I get homesick and feel nauseous sometimes on normal vacations... I bet you, if they actually pulled off the feeling of being on a ship in space for this as well as they do the Star Destroyer for Rise, that I would get pretty claustrophobic and sick that first night. But hey, then the next morning I get to take a shuttle down to Batuu and have a breakfast Ronto Wrap so it's all good!
